Mendel studied seven characteristics in peas including seed texture, seed color, flower color, flower position, stem length, pod shape and pod color. He started his pea breeding program by allowing certain pea plants to repeatedly self-fertilize. ... Heterozygous (one of each gene type) for flower color Pp = purple flower...

Dominance (genetics) - Wikipedia, the free encyclopedia
In genetics, dominance describes a relationship between different forms (alleles) of a gene at a particular physical location (locus) on a chromosome. Typical plants and animals have two sets of chr...

In Mendel's garden pea experiment, ... Both males and females can express the trait unless it is a recessive sex linked gene. ... The examples of dominance in the garden peas were flower color and seed shape. But in other plants the flower color is not necessarily one color or the other, meaning that the plant may express a...

By studying the characteristics of pea plants, such as their height, seed shape, seed color, flower position, and other traits. this discussion will use height as a primary example. Mendel first crossbred ... In sex-linked traits, such as color-blindness, the gene for the trait is found on the X chromosome (a sex chromosome).

During this time, Mendel observed seven different characteristics in the pea plants, and each of these characteristics had two forms (Figure 3). The characteristics included height (tall or short), pod shape (inflated or constricted), seed shape (smooth or winkled), pea color (green or yellow), and so on.

Each of the traits that Mendel observed in his pea plants came in one of two varieties; ... The color and shape of the pea seeds provided two convenient traits to study. ... For instance, if the genes for seed shape and seed color were on the same chromosome and a homozygous double dominant (yellow and round, RRYY) plant was...

Traits - characteristics - 7 traits in pea plants: seed shape; seed color; ... Genes - factors that control traits. Allele - alternate forms of a gene - one possible form of that gene or trait. Ex. gene for seed color - allele for green and a allele for yellow. ... Sex linked gene - gene located on a sex chromosome.
